Background The importance of measuring aortic pulsewave velocity (PWVao), aortic augmentation index (Aix) and central systolicblood pressure (SBPao) has been shown under different clinical conditions;however,information on these parameters is hard to obtain. The aim of thisstudy was to evaluate the accuracy of a new, easily applicable oscillometricdevice (Arteriograph), determining these parameters simultaneously, against invasivemeasurements.

Methods Aortic Aix, SBPao and PWVao were measuredinvasively during cardiac catheterization in 16, 55 and 22 cases, respectively,and compared with the values measured by the Arteriograph.
